A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2011. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
The space rock, measuring 1,230 feet (375 meters) across, will come closer to our planet than satellites in its orbit and 10 times nearer than the moon. Apophis will come so close to Earth that it ...
“Close,” in the space world, is a relative term. At its nearest, Apophis will pass roughly 19,000 miles (31,000 kilometers) above Earth’s surface. That's about one-10th the distance to the moon.
The asteroid will pass 0.00516 AU (772,000 km; 480,000 mi) from Earth on 27 December 2022, [4] [5] allowing a refinement to the known trajectory. The uncertainty region in 2013 suggested that the asteroid could have passed inside the orbit of the Moon in 1907, but is now known to have passed about 0.01 AU (1,500,000 km; 930,000 mi) from Earth ...
The spacecraft will hit the moon nearly head-on at a speed that's faster than a bullet. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please call: 800-290-4726 ...
